Review & Installation Video

Hey guys, Stephanie with here with my review and Dyno test of the JLT cold air intake available for your 2012 and 2013 Boss 302. The JLT cold air is going to be for the Boss 302 owners out there or even the '11 to '14 GT owners who've installed a Boss intake manifold who are looking for a top rated quality intake that will provide some solid gains in both power and sound compared to the factory air box and will look good under the hood while doing so. I should point out that the JLT is a tune required intake, so you can't just bolt this thing up to your Boss or GT without a custom tune. I'll explain why in a minute. First, let's get to some Dyno numbers. We already established a baseline run earlier today using the '13 Boss behind me. We then went to work installing the JLT along with a custom tune as required, reran the car, and here are those numbers. Our baseline run with our 2013 Boss gave us numbers of 387 horsepower and 333 foot-pounds of torque at the rear wheels. With the JLT intake and the 93 octane VMP tune the car made 398 horsepower and 337 foot-pounds of torque, making for a peak gain of 11 horsepower and 4 foot-pounds of torque. By opening up some air flow in those upper RPMs we ended up seeing 15 horsepower at 7400 RPMs and 10 foot-pounds of torque at 7000 RPMs. Keep in mind that we did pair the intake with a tune. A lot of these gains can definitely be attributed to that tune. As far as curve gains, you can see right here that there isn't a whole lot going on in the graph. The factory intake is actually really efficient. Like I said, not a ton of curve gains, but all of the gains are going to be in the upper RPMs where the stock air box starts to become restrictive. With the numbers out of the way, let's dive into the JLT. In my opinion JLT is one of the most trusted and recognizable names in the cold air market for the late model Mustang. The numerous five star reviews on the site reflect that. As I mentioned earlier, the JLT is a tune required intake. That's due to the large 107 MAF air flow housing, currently the largest available on the site for the S197 Boss intake manifold. The larger MAF housing and intake tube should allow your Boss or GT to breathe easier and will traditionally make a little more power when compared to a no tune required intake because of the larger MAF housing and intake tube. JLT keeps more of a simplistic design with this intake. The intake is all business. They don't use any flashy finishes or any gimmicks to separate their products from the others. One thing I do like about the JLT design is that they incorporate the MAF housing into the tube itself which just looks cleaner in my opinion. Some other options use a separate metal MAF housing along with a plastic tube. There's nothing wrong with that from a performance standpoint, but it just doesn't look as nice to me. In addition to the tube and MAF housing, the rest should look pretty familiar in the world of aftermarket intakes - reusable high flow S&B oiled filter, an open element style heat shield which does tap into the factory cold air duct which is a nice touch, and finally all of the hardware and couplers to wrap everything up. The JLT will obviously work with a factory throttle body without issue, but it should also work with any aftermarket 85 millimeter or 90 millimeter throttle body without an issue as well. Another nice thing to point out is that the JLT includes a foam plug to insert into the portion of your GT's hood vent to prevent water from getting into your filter. Believe me, it's something that you're going to want to use as the filter does sit right below the lower portion of the hood vent on the driver side. Thumbs up to JLT for including this. Even with these extras and the solid construction and the largest on the market MAF, the JLT is still coming in at a very reasonable price point coming in right around the $300 price mark. A brief rundown of the install. Basic hand tools here, guys, including a socket set, a few screwdrivers, a pair of pliers and a Torx tool for the MAF sensor is really all you need to remove the factory intake and get the new JLT into place. I will say assembling the intake first outside of the car will make life a little bit easier along with installing the heat shield first. This is overall basic stuff that any novice should be able to tackle with ease. All in all this is going to be a 1 out of 3 wrenches on the scale and, guys, maybe about 30 minutes to an hour depending on your experience. As far as my recap, here's what I think. The JLT is one of the top rated intakes on the site and it's easy to see why. When paired with the required custom tune option, the power improvements are going to be tough to beat given the price point. Be sure to learn more about ways to add power to your Boss right here at

More Usable Horsepower. Gain easy HP and TQ throughout your power band with a JLT intake and a custom tune on your 2012-2013 Boss or 2011-2014 GT (with Boss intake installed). Putting 30 more ponies to the pavement doesn't get any easier, faster, or more affordable than this. Plus, your Boss will also respond faster with a noticeable improvement in throttle response for better driveability and quicker launches.

107mm MAF Housing. This JLT cold air intake kit has a unique design that incorporates 107mm MAF housing right into the tube for a clean look (MAF not included). Plus, a removable cap over the interior sound tube allows you to choose whether you want to hear the added growl from your new intake or not.

Heat Shield Included. The JLT Performance Cold Air Intake includes a vacuum formed ABS plastic heat shield that not only looks great, but blocks out excessive under hood engine heat at low speed and idle that can rob you of power.

Money Saving Reusable Filter. This JLT cold air intake kit comes complete with a high flow reusable S&B brand air filter. So that means there is no need to go out and buy a new filter every few thousand miles. Now you can just clean the filter, re-oil it, save money, and go!

Required Upgrade. Installation of this Cold Air Intake will require the use of a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for operation.

Application. This JLT Cold Air Intake is specifically designed for use on the 2012-2013 Boss or 2011-2014 5.0 GT Mustang with the Boss 302 Intake Manifold installed. Requires a new computer tune. Works with manual or automatic transmissions.

Technical Note. Automatic equipped Mustangs will require drilling an extra hole into the induction tube for proper installation.

I have a 85mm BBK throttle body with my boss 302 manifold. What makes this intake different from the regular JLT intake? And will this one fit my Throttle body

  • The JLT Performance Cold Air Intake for the Boss intake has the couplers designed specifically to fit the Boss Intake's revised throttle body angle. The coupler is designed to accommodate larger aftermarket throttle bodies, as well as the OEM throttle body.

Would it really be that big of a deal with I bought this one by accident and don’t have a Boss intake manifold? I know the tubing and filter are the same, but will it not fit based solely on the heat shielding?

whats the difference in this jlt intake(62055) and the other jlt intake(62030) they both fit the 2013 boss 302 and they are the same price. thanks!

  • Hey Jane, The only difference in the two is the heat shield attached to the filter. 62055 heat shield is designed for the boss in terms of where it sits. the filter, and tubing are the same

    Great sound

    It was between the JLT and the Steeda for me since both offer the most gains. I've ran steeda before and it really is amazing, but I knew I wanted to buy the Boss 302 intake manifold, so I went with this (Steeda offers fitment for the boss 302 manifold but you would have to contact them directly). YES you do need this CAI if you are going to install the boss 302 manifold. I had called before and they told me I needed the other JLT CAI for the GT and the coupler is too small to fit so I had to wait another week for install. Just fwi... Between the two prices for the V8, I'm giving it to JLT for the best bang for buck. LOVE the whistle it makes, easy fitment, NO issues. Wish they offered different colored cones but that's not an issue. Install took 5 minutes tops. I think they claim to have a 20 hp gain but I don't think so (maybe with a dyno.). I would say with a bama tune, you're looking at an extra 7-8 horses. STILL noticeable gains, and great price.

    Fitment issues!!! But great throttle response!!!

    It took me a while to install this because after the install the Air Filter kept hitting the hood when I closed it. I was frustrated and had to tweak and peak the intake a little but once installed the throttle response was drastically improved. This thing sucks so much air that you can hear it from your cab. Im impressed and can't wait to see the power gains.

    Great product! Easy to install

    I bought this intake along with the Boss 302 manifold for my 2012 GT, the fit perfectly together. Installation was a breeze with step by step instructions. It only took an afternoon to install both. With a Bama tune this setup completely woke my car up! It's a whole new feel and there is no loss of power in the low rpms. This is a great starting point for adding big power upgrades later. I would definitely recommend this to anybody.

    Easy peasy install

    I was in the market for a CAI that would work with a 302 Boss intake manifold that I just purchased from American Muscle. I wanted one that worked together and was best fit for the Boss intake and the experts at American Muscle recommended the JLT. I installed it on my 2014 Mustang Gt in under an hour. Installation was extremely easy with the step by step directions. This was an excellent choice and great recommendation from American Muscle. Thanks AM

    Good intake but not the best

    I bought this at the same time I bought a BOSS manifold for my 2013 GT. The install is very easy and should only take 15 minutes or less. The fit and finish is great. I like this intake because of its "stock" appearance. My only issue with this intake is the whistle that you get when at about 10% throttle(right where you need to be to maintain speed on the highway). At the perfect throttle position you can hear a loud whistle coming from the intake. It can easily be heard if the windows are up with the radio off. This does not effect the performance of the intake, but until you get used to it, it will drive you mad.
